Is there any real difference between 23mm and 25mm tires as far as
speed. Will 2mm make you that slower or faster?
thanks, Jeff

I used to use 23 mm tires exclusively. Fashion I suppose. I now use
mostly 25mm tires. I can't tell any difference in speed, comfort,
traction, flat rate, or anything else.
